O<sub>3</sub> and Drought Effects on Steady State Conductance and Kinetics in Pima Cotton

چکیده

The degree to which ozone (O 3 ) exposure and drought affect stomatal control of water loss respond environmental stimuli such as varying light is poorly characterized. To that end, we exposed Pima cotton chronic O (month-long daytime exposures) with without sufficient water, well short term acute levels understand kinetics. Chronic, month-long moderately high (~114 ppb) reduced steady state conductance (g s ), did deficit. Both opening closing displayed dose specific, “sluggish” responses step-changes in illumination acute, 1-day, exposures 0, 50, 100, 125 ppb. At higher concentration (150 ppb), both was degraded. Altered dynamic function suggest elevated ambient , expected increase the future, may increasingly influence field management appropriate crop choices.
